LKH has someone (I think Sampson) say in this book that Valentina is interested in sex mentally, but she can't physically do it because she is too "delicate" (though she's a vampire), and therefore she is evil. Which makes no sense on any level. Valentina never came close to puberty, and not having sex does not evilify someone, and if she ACTUALLY is a 500-year old grown woman trapped in a 5 year old's body there would be ways around that though I don't want to think about it -- but there it is.
